TBH I actually haven't looked at them that closely in ages so I have no idea.
Up close they scream fake, but I think those for characters/cards that were never released (like ur 8D8 POTF) are pretty cool and pretty harmless. I mean no one but a newbie would think they were actually genuine, and even if they do and end up buying them they won't get stung for much more than £20-£30.
Though that's not me condoning fakes/recards en masse!
